There is nothing concrete here, because there is no game. The game isn't profitable, the marketing is. No investor (bank, commercial finance company, etc.) will hang their hat on CIG because, at the end of the day, there has to be a product to give the customers. So far, the return for customers (and we can call anyone putting money into this thing post-Kickstarter a customer, due to sales tax, and ship sales - not "ship pledges") has been "well, maybe next year." Much like publishers, actual investors also believe in accountability.
There is no "Therefore the game will be made without question," because there's nothing concrete pointing to that to even make it resemble a fact. And yes, everyone expects something different from SC, because absolutely nothing has been defined. Nothing is firm. Not the eventual end product. Not the roadmap. Hell, even the specs on their "sold" assets end up losing seats. This is why CIG scaled back from farming, news vans, and everything else that actually *creates* more gameplay mechanics and problems, to a nebulous "MVP" that has no timeline to check. The MVP is something they shifted gears toward AFTER they realized they couldn't deliver, not something they were striving toward all along, and planing on building upon it as a strong foundation.
EDIT: This is ultimately what will drive people to find that "unacceptable" line (which quite a few backers have already reached, going by the refunds) - THERE IS NO FOCUS. What is SC? Is it roleplaying? Is it FPS? Arcade space battles? A genuine space sim (there is that space bike, after all)? Trading? Espionage? A 'verse where both men AND women coexist? Can players really have it all? Trying to be too many things to too many people, instead of finding your true audience, will just end up disappointing and frustrating everyone, driving them to find the games that actually DO have the features they want, rather than pale elements mashed together in a very grey...thing.
CIG has zero accountability and zero oversight. That does not make for a good business, especially when no one (not even the backers) can say where their "funding" is going.
